Volkswagen’s Electric Turbo Engine

There is one major drawback for turbocharged engines. The drawback  is called “turbo lag”, which means the turbo cannot enter into full boosting mode before there is enough exhaust gas to spool up the turbine.  This builds up boosting pressure! What does that mean? It means there is always a delay between the time that an engine receives command to provide high output, therefore the engine can actually provide that amount of output.

There is one solution comes to mind,  Don’t let the turbocharger depend on the exhaust gas to spool up.

This is how an electric turbocharger comes into play

The idea is pretty straightforward...
